6c2be2b8 - [SILOptimizer] Prevent devirtualization of call to distributed witness requirements

[SILOptimizer] Prevent devirtualization of call to distributed witness requirements This is a narrow fix, we are going to work on fixing this properly and allowing both devirtualization and specialization for distributed requirement witnesses. Anything that uses an ad-hoc serialization requirement scheme cannot be devirtualized because that would result in loss of ad-hoc conformance in new substitution map.
